White Space is the name given to the empty pieces of spectrum in between TV Broadcasting channels. The bandwidth required per channel was pretty big while analog transmission was used, but with the advent of Digital Video Broadcasting in Europe, cable and other methods of watching TV, these areas are increasingly open.

Potentially, using these free spectrum, one could transmit data at very high bit-rates, leaving current WiFis antiquated. This is the reason for WiFi 2.0, also known as WiFi on steroids.

The FCC just voted unanimously to open these spectrum areas for companies to start doing research on new ways to transmit wireless data. Google, that had previously tried – with no luck – to actually buy some spectrum to perform this kind of research, was already very interested in this increasingly empty spectrum. Back in 2008, Google had already proposed to convert White Space into unlicensed bandwidth for long-distance wireless broadband applications.

This morning the Federal Communications Commission adopted final technical rules related to white spaces – the empty airwaves between broadcast TV channels – that we believe will pave the way for “Wi-Fi on steroids.”

For several years now, the tech industry, the public interest community, and entrepreneurs have been clamoring for the green light to begin innovating and building new products for these airwaves on an unlicensed basis. Today’s order finally sets the stage for the next generation of wireless technologies to emerge, and is an important victory for Internet users across the country.
